Remarks

  • The signature for this tag type is IccTagTypeBase.ResponseCurveSet16TypeSignature.
  • The purpose of this tag type is to provide a mechanism to relate physical colorant amounts with the normalized device codes produced by lut8Type, lut16Type, lutAToBType or lutBToAType tags so that corrections can be made for variation in the device without having to produce a new profile.
